EDWIN IMO REY, OF NASHUA, NEW HAMPSHIRE, ASSIGNOR TO IMPROVED PAPERMACHINERY COMPANY, OF NASHU'A, NEW HAMPSHIRE, A CORPORATION OF MAINE.

WINDING-MACHINE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, EDWIN MOREY, a citizen of the United States, andresident of Nashua, New Hampshire, have invented an Improvement inVVinding-Machines, of which the following description, in connectionwith the accompanying drawings, is a specification, like characters onthe drawings representing like parts.

This invention relates to machines for winding paper in the form oftubes and for other purposes.

The character of the invention may be best understood by reference tothe following description of an illustrated embodiment thereof shown inthe accompanying drawings, wherein:

Figure 1 is a front elevation of an illustrative winding machine shownherein as embodying the invention; Fig. 2 is a vertical section taken online 2-2 of Fig. 1; and

Fig. 3 is a vertical section taken on line 3'3.

of Fig. 1.

Referring to the drawing, the illustrative machine shown therein asembodying the invention comprises a frame 1 associated with a paper pulpcontaining vat (not shown)- containing a mold cylinder 3. Cooperatingwith the mold cylinder is a couch roll 5 and a web carrier 7. The aboveparts may be of usual well known construction and are adapted to form aweb of paper from the pulp in the vat. The web of paper is conveyed bythe carrier to a suction or base roll 9 of any suitable or usualconstruction. The web .of paper may be transferred to and wound on atubular mandrel 11 of aluminum or other suitable material.

The mandrel shown is of small diameter and considerable length andtherefore is liable to bend axially and destroy the uniformity of thewinding of' the paper web thereon unless provision is made formaintaining the mandrel in straight axial alinement. To this end thereis provided a presser roll 13 of substantial diameter and weight, saidroll being journaled in bearings in a frame 15' on free ends of arms 17pivoted to-brackets 19 projecting fromthe machine frame.

An important feature of the invention relates to the relation of thispresser roll with the mandrel. As shown herein, the mandrel base roll isrotated in a contra-clockwise direction and the mandrel isfrictionally'ro- 'tated thereby in a clockwise direction. The

presser roll is mounted to bear on the mandrel at a line offset somewhatfrom the left (Fig. 2) of a straight diametrical line common to andpassing through the base roll and mandrel centers. Tangent lines, if

drawn through the points of contact of the mandrel with its base andpresser rolls, would converge to the left of said figure. The mandrel inrotating tends to work itself toward the apex formed by said tangentsand thereby tends to crowd itself in between the base and presser rolls,and prevents any bellying of the mandrel or departure thereof fromstraight axial alinement. The use of a single presser roll in preventingdistortion of, the mandrel is extremely advantageous, since the rollcontacts with the soft paper pulp being wound on the mandrel along butone line of contact, and thereby a uniform pressure is maintained bn themandrel tending to produce a paper tube of uniform compactness andconsistency throughout.

The rotating of the cylinders and rolls described will wind the paperweb on the mandrel until a desired thickness of tube or material isobtained. On the occurrence of this event it is desirable to remove themandrel from its active winding position between the base and presserrolls and to substitute an empty mandrel therefor.

An important feature of the invention relates to mechanism for shiftingthe manvdrels to and from actiie winding position. To this end there isprovided a carrier 21 comprising spaced elongated heads 23 fast on ashaft 25 journaled in bearings in the frame 1, said heads being providedwith bosses 27 in which are journaled shafts 29. Fast on these shafts.are arms 31 having suitable provision for detachably.supporting' themandrel 11, referred to, between their 'free ends. As shown herein, thecarrier is provided with two sets of diametrically opposed arms such asdescribed for supporting two mandrels, one in active and the other ininactive position. It will be understood, however, that the carrier maybe equipped to accommodate any desired number of mandrels. The carrieris rotated at appropriate intervals to withdraw one of the mandrels fromactive winding position and substitute an empty mandrel therefor. Tothis end the carrier shaft 25 is provided adjacent one end thereof witha friction disk 35 (Fig. 1) fast thereon coiiperating with a secondfriction disk 37 loose on a reduced portion of said shaft. The disks 35and37 are constructed and arranged with approintimate frictionalengagement.

chine frame. provided with a. large sprocket wheel 47 driven by a.sprocket chain 19 from any appropriate source of power. A

Sincethe friction disk 37 is continuously rotated it will continuously,tend to rotate the friction disk 35 and the shaft and mandrel' carrier.The carrier must be locked against rotationwhile the mandrel isbeingwound. To this end the carrier is provided with an end plate 51 (Fig. 2)having a notch at its-lower end coiiperating with a locking lug 53 on asliding plate 55 supported on the machine frame by pins 57 enteredthrough elongated slots 59 in said plate. The locking plate is normallyheld up to present the lug 53 in locking engagement with theplatenotchbya helical spring 61 interposed between the lower end of said plate and abracket 63 projecting laterally from the frame 1.v By moving the lockingI a plate downward the lug 53 will release the pivoted on a pin 87 plate55 referred to.

plate 51 and'the carrier will be rotated. in a contra-clockwisedirection (Fig. 2) by its.

frictional driving mechanism described.

As shown herein, means is provided for automatically releasing the locklug by the movement of the mandrel arm 31 asit is rocked upward by theincrease of material' wound thereon. To this end each rocking mandrelarm is provided with a" dog 65' (Eig. 2) for engagement "with an arm 67fulcrumed on a pin 69 carriedsbya bell crank lever 71 fulcruined on apin 73 projecting from the frame 1'. One arm of this bell crank lever isprovided with an elongated slot '75 for receiving a pin 77. projectingfrom the lockplatefor a purpose to bedescribed. The rocking movement ofthe arm 67 istransmitted by an adjusting screw 79 to a lever 81 alsopivoted on the pin 69, said lever intur'n being provided with an adjusting screw 83 for engagementwith a dog 85 projecting from the lockContinuously rotated adjacent the end of the dog 85 is an arm 89 fast onthe shaft45 levers 115' fulcrumed on the shaft 45 re .ferred to. r Torock theselevers and lift the I referred to. When a predetermined amountof material has been wound uponthe active mandrel 33 its supportingarm31 will have rocked suflicientlyto cause its dog 65 to engage the arm 67-androck the latter, this movement being transmitted to the lever 81throughthe screw 79. The lever 81 then rocks the dog 85 mto the range ofthe continuously rotated'arm 89. On the occurrence of'this event the arm89 will. engage the dog 85 and operating through the latter, will slidethe locking plate 51' downward against the resistance of its spring,thereby releasing the lug 53 from the locking plate notch and permittingthe mandrel carrier to be rotated by its frictional driving means towithdraw one of the mandrels from active position and introduce anotherof said mandrels into active position. v

The mandrel carrying arms are free to swing on the carrier. Therefore,in the course of the rotation of the carrier in shifting the mandrels,said arms would tend to swing and depend downward. As a result, thefilled mandrel might drag objectionably along the surface of the web onthe roll, with liability of injuring the soft paper tube on saidmandrel. It is, therefore, desirable to positively control and guide themandrel swinging'arms in the course of the rotation of the carrier. Tothis end each of the -mandrel arm shafts 29 is provided with acontfollin-g arm 101"(Fig, 3) having at its free end a roller103received in and guided by apwithdrawal cam slot 105 andanintroductioncam slot 107 in a-plate 109 at one .end of the carrier andsecured to' the machine frame. The entrance end of the withdrawal camslot 105 is so formed that on the "initial rotation of the carrier themandrel is immediately lifted up out of engagement with the base roll.The continued rotation of thecarrier will cause the mandrel to be guidedthence to the position shown at the left of Fig. 3 at the front of themachine. Here the mandrel is readily accessible and may be manuallyremoved from its arms and an empty mandrel substituted therefor. Afteran empty mandrel has been placed on the arms the latter are manuallyswung over to present the mandrel in the position shown 'in dotted linesat111 (Fig. 3)- In this position the guide rolleris at'the entrancethroat of the introduction camslot 107 in readiness to be guided by thelatter into-active position for winding on the next rotation of thecarrier. Thus the rotation of the latter simultaneously automaticallywith, draws a full mandrel from active position and substitutes an emptymandrel therefor.

Before a mandrel can be shifted to and from active position the presserroll should be lifted 'out of engagement therewith. To

this end the presser roll frame 15 (Figs. 2 a

and 3) is connected by vertical rods 113 with presser roll up out ofengagement with the mandrel they are extended beneath cams 11? ed fastbna shaft 121 journaled inbearings in the machine frame and parallelin thehaving flat faces 119,;said cams being mount.

the shaft 45 is provided with a spur gear 123 fast thereon driving agear 125 loose on the shaft 121. To transmit the drive from the gear 125to the shaft 121 they are provided with cooperating friction disks 127and 129 (Fig.1). i

,To normally lock the'sha ft 121 against rotation it is provided at oneend thereof with a dog 131 (Fig. 2) engaging a lug 133 projectinglaterally from the lock plate 55 referred to. When the lock plate isslid downward as described, first the lug .133 will escape beyond theend of the dog 131, thereby permitting the shaft 121 and the camsthereon to rotate, causing said cams to engage the levers 115 and j tiltthem, thereby lifting the rods 113 and 'the'presser roll 13 up out ofengagement with the mandrel.

Continued downward movement of the lock plate will cause the lug 53 torelease mechanism to shift a filled mandrel from windin position andsubstitute an empty mandre therefor as described. In the course of thisshifting movement the lug 53 is pressed by the spring 61 into engagementwith the edge of the carrier 51 which is formed to permit the upwardmovement of the lock plate under the action of said spring and therebybring the lug 53 in position to catch into a diametrically oppositenotch of the" lock plate and limit the rotation of the carrier. Thenotches in the carrier plate thus serve to determine the active windingposition of the mandrel. The carrier is held firmly against one or theother of the lugs by the tendency to drive the carrier shaftcontinuously through the friction disks 35 and 37 referred to.

The carrier with its swinging mandrel guided and controlled in theirshifting movements by the cam slots as described.

In order to permit tubes of varying thickness to be wound the screws 79and 83 may be adjusted to cause the mandrel. operated dog 15 to engagethe arm 67 earlienor later as desired.

To prevent interference bythe arm 67 with the mandrel arm operated dogin theretreat of the mandrel from activeposition the bell crank 71 isrocked about its pin 73 as a fulcrum to move the arm 67 out of rangewith the dog 65, this movement being effected by the sliding of the pin77 in the elongated slot of said bell crank when the 'lock plate is sliddownward to release the locking lug 53 from the carrier plate 51. Sincethe carrier cannot rotate until the locking plate has been moveddown thepreventing of interference with the dog 65 is assured.

burden of supporting a heavy mechanism for shifting it and enables thefree swinging movement of said arms as the pulp layer accumulatesthereon. 1

lBy the construction and arrangement of v the presser roll 13 themandrel is maintained in straight axial alinement and thus is pressedequally by said presser roll throughout itslength. On the completion ofthe winding of the pulp on a mandrel the presser roll is automatically,mechanically lifted out of engagement with the mandrel by a simple andeffective mechanism While the invention has been described herein asembodied in a paper tube winding. machine, it will'be understood that itis not limited ,thereto, but is obviously applicable to machines forother purposes.
